This is what you said
"Monko/ Khaliavin RUS
SD More, sung in French; Polka (anyone know which polka?)"

I don't know what you meant by "More, sung in French" ?
While it is obviously in French, that song is an iconic chansonette, sang by the famous actor and singer Yves Montand "Sous les ciel de Paris" (Or "Under the sky of Paris"):
